Best Practices

​

Organizing Queries

1. Use descriptive comments: Add comments to important queries
2. Test queries first: Build up complex queries incrementally
3. Save important queries: Copy critical queries to files
4. Regular cleanup: Clear history periodically if needed

​

Development Workflow

1. Iterative development: Build on previous query attempts
2. Error learning: Review failed queries to avoid mistakes
3. Pattern reuse: Find similar queries for new requirements
4. Performance comparison: Compare execution times

Troubleshooting

​

History Not Saving

1. Check settings: Verify history is enabled
2. Storage permissions: Ensure VS Code can write to workspace
3. Memory limits: Check if storage quota exceeded
4. Restart extension: Reload Koala Data Explorer

​

Performance Issues

1. Large history: Clear old entries
2. Complex queries: Large SQL statements may slow search
3. Search optimization: Use specific search terms
4. Limit results: Reduce history display size

​

Missing Queries

1. Execution status: Only completed executions are stored
2. Connection issues: Failed connections may not save
3. Storage errors: Check for storage problems
4. Manual execution: Only manual queries stored (not automated)
